The photonic structures occurring in Calliphora vicina and Lucilia richardsi’s cuticle were modelled by multilayer periodic reflectors made of a stack of two different kinds of layers with thicknesses d_i and d_j, magnetic permeabilities μ_i = 1 and μ_j = 1 as well as dielectric permittivities ε_i = 1.68² and ε_j = 1.55² [75]. The incidence medium and the substrate have, respectively, magnetic permeabilities μ_inc = 1 and μ_sub = 1 as well as dielectric permittivities ε_inc = 1.00² and ε_sub = 1.68² [75]. Vector $\vec{k}$ represents incident wave vector.
